Marsh will have his right knee examined by team doctors after he tweaked it on a play in center field during Wednesday's loss to the Giants, Todd Zolecki of MLB.com reports.

EDGE Analysis

Marsh is mired in a 0-for-31 slump, but it's evidently the knee that's keeping him out of the lineup for Thursday's series finale. It's not clear whether the 10-day injured list might be a possibility for the outfielder, but the Phillies should have more on his condition later in the day. Johan Rojas will start center field and bat ninth Thursday.
